	* elf/dl-support.c: Include dl-procinfo.h.
	* sysdeps/powerpc/dl-procinfo.h (PPC_PLATFORM_POWER4,
	PPC_PLATFORM_PPC970, PPC_PLATFORM_POWER5, PPC_PLATFORM_POWER5_PLUS,
	PPC_PLATFORM_POWER6, PPC_PLATFORM_CELL_BE, PPC_PLATFORM_POWER6X):
	Define.
	(_dl_string_platform): Use PPC_PLATFORM_* macros instead of
	hardcoded constants.
	* sysdeps/powerpc/dl-procinfo.c (_dl_powerpc_platform): Use
	PPC_PLATFORM_* macros for array designators.

2006-11-11  Steven Munroe  <sjmunroe@us.ibm.com>

	* sysdeps/powerpc/dl-procinfo.c (_dl_powerpc_cap_flags): Add 3 new cap
	names to the beginning.
	(_dl_powerpc_platforms): Add "power6x".
	* sysdeps/powerpc/dl-procinfo.h (_DL_HWCAP_FIRST): Decrease.
	(HWCAP_IMPORTANT): Add PPC_FEATURE_HAS_DFP.
	(_DL_PLATFORMS_COUNT): Increase.
	(_dl_string_platform): Handle power6x case.
	* sysdeps/powerpc/sysdep.h (PPC_FEATURE_PA6T, PPC_FEATURE_HAS_DFP,
	PPC_FEATURE_POWER6_EXT): Define.
	(PPC_FEATURE_POWER5, PPC_FEATURE_POWER5_PLUS): Correct Comment.
